Details

As written in the advisory (Markdown source, shown as plain text).

### Impact Security researchers at Trail of Bits discovered that plugin names are not sanitized properly. As a result, a malicious plugin author could use characters in a plugin name that would result in unexpected behavior, such as duplicating the name of another plugin or spoofing the output to `helm --help`. ### Specific Go Packages Affected helm.sh/helm/v3/pkg/plugin ### Patches This issue has been patched in Helm 3.3.2. ### Workarounds Do not install untrusted Helm plugins. Examine the `name` field in the `plugin.yaml` file for a plugin, looking for characters outside of the [a-zA-Z0-9._-] range.
